. STEAM ISEPARATOR.

Application led March 11, 1927, Serial No. 174,495, and in Great Britain January 13, 1927.

This invention has reference to steam separators for use in steam generators of the kind wherein moisture and sediment borne by the steam are removed therefrom before the steam leaves the generator thus ensuring dry clear steam.

According to this invention a steam separator comprises a dry steam chamber divided into two or more vertical compartments by one or more imperforate walls having angularly set ribs or fins, the dry steam chamber communicating at the top with the steam outlet and having a sump below, also having an opening or openings in the peripheral wall into which scoured steam, denuded of any solid matter it may have contained and of most of its moisture, in a suitable scouring chamber or chambers, is admitted, the scoured steam being linally dried in the dry steam chamber, the water taken therefrom in the dry steam chamber flowing into the sump below.

rlhe invention is more particularly set forth with reference to the accompanying drawings wherein- Fig. 1 is a front elevation ofk a steam separator according to this invention, partly in section.

F ig. 2 is a plan thereof, and

Fig. 3 is a part sectional end elevation and Fig. 4 is a front view of` a wall or plate used in the dry steam chamber.

Referring to the drawings, the dry steam chamber 4 is in the form of a drum having open ends, the top having a flange 5 and bolts whereby it may be secured to the fitting 6 whereby this part of the apparatus is secured to the steam generator shell to communicate with the steam pipe, not shown in the drawings. The bottom of the steam chamber 4- is closed by a sump 7, conveniently deeply dished or part spherical. The peripheral wall of the dry steam chamber 4 has two diametrieally opposite openings 8 and 9 by which scoured steam from scoured steam passages 10 of scouring chambers 11 which are connected to the dry steam chamber as projecting arms, is admitted. The top 14 and bottom 15 and outer ends 16 of the scoured steam passages 10 in each scouring chamber 11 are imperforate and the side walls are formed by batteries of baiiies 12 all communicating directly with a sludge chamber 13 below, which as will be readily under'- stood is isolated from the scoured steam passages 10 in the middle of the scouring chamber 11 above, by the imperforate bottom 15 thereof.

The openings 8 and 9 in the peripheral wall of the dry steam chamber 4 are of a diameter or' width not exceeding the width of the scoured steam passages 10, and the chamber itself is divided vertically by an imperforate wall or plate 17 extending diametrically from one side of one opening 8, to the opposite side of the opposite opening 9. This imperforate wall or plate 17 has iins or ribs 18 projecting from it on both sides and pointing toward the scoured steam passage or passages 1() with which that compartment of the divided dry steam chamber 4 is connected. These fins or ribs 18 may be arranged vertically as illustrated, or horizontally or angularly on the wall or plate andv may be broken or unbroken but, whatever the formation or arrangement, theywill form traps or pockets into which the scoured steam will rush till it is caused to change direction abruptly by contact with the wall or plate as it passes upward to and enters the steam` pipe.

Any water which may be carried by the scoured steam, as for instance, at a peak load into the dry steam chamber 4 will be deposited on the wall or plate 17 and on the fins or ribs 18 and will drip into the sump 7 below, which if desired may be separated from the dry steam chamber by a floor having a suitable drainage opening below the plate or wall and the fins or ribs. v

At the lowest points the sludge chambers 13 below the scoured steam passagesare connected to a blow off pipe 19 leading to the outside of the generator to which or to a separate pipe, the sump 7 of the dry steamy chamber 4 may be connected, thus preventing the direct ingress of a steam thereto, and the sludge chambers are also provided with water escape pipes controlled by one way valves 2O by which water which has reached a high level in the sludge chambers may return to the water in the generator, but which will prevent the ingress of water to the sludge chambers.

rThe end plates 16 of the scouring chamber 11 are provided with extensions or brackets 21 adapted to take bolts by -which the ends of the appliance may be secured to the generator shell.

It is to be understood that while the invention has been described and illustrated as having a single wall or plate, a plurality oit such walls or plates may be used.

Vihat I claim as my invention and desire to secure by Letters Patent is l. A steam separator for use in steam generators comprising a scouring chamber and a dry steam chamber divided into vertical compartments by an imperitorate wall having angularly set ribs or tins, said dry steam chamber communicating at the top with the steam outlet and havinga sump below, said dry steam chamber also having an opening in its peripheral wall into -which scoured steam, denuded et' any solid matter it may have contained and most of its moisture in the scouring chamber, is admitted, the scoured steam being tinaliy dried in the dry steam chamber, the water taken therefrom in the dry steam chamber tlowing into the sump below.

2. A steam separator for use in steam generators comprising a scouring chamber and a dry steam chamber divided into vertical compartments by an imperiiorate wall having angularly set ribs vor fins, said dry steam chamber communicating at the top with the steam outlet and having a sump below, said dry steam chamber also having an opening in its peripheral wall into which scoured steam, denuded of any solid matter it may have contained and most of its moisture in the scouring` chamber, is admitted, the scoured steam being inally dried in the dry steam chamber, the water taken therefrom in the dry steam chamber flowing into the sump below, a passageway formed in said scouring chamber in communication with the opening in said dry steam chamber, said passageway having an imperforate bottom and side walls formed by a plurality of baiiies, and a sludge chamber separated from said passageway by said imperiorate bottom and in communication with said battles.

3. A steam separator for use in steam generators comprising a scouring chamber and a dry steam chamber divided into vertical compartments by an imperiorate wall having angularly set ribs or tins, said dry steam chamber communicating at the top with the steam outlet and having a sump below, said dry steam chamber also having an opening in its peripheral wall into which scoured steam, denudcd of any solid matter it may have contained and most ot its moisture in the scouring chamber, is admitted, the scoured steam being` finally dried in the dry steam chamber, the water taken therefrom in the dry steam chamber iiowing into the sump below, a passageway' 'formed in said scouring chamber in communication with the opening in said dry steam chamber, said passageway having an impertorate bottom and side walls formed by a plurality of battles, a sludge chamber separated from said passageway by said imperiorate bottom and in communication with said battles, a relie't pipe communicating with said sump and sludge chamber, and a one-way valve co1nmunicating with said sludge chamber to permit the escape ot' water therefrom.

4. A gas separator comprising a plurality ot' sect-ions, a T having a gas chamber with two inlets, said T connecting two of said sections, each of said two sections having a gas conduit therein, each of said conduits communicating with one of the inlets ot said chamber, and a partition in said chamber separating said inlets.

5. A gas separator system comprising a T having an outlet, on one side andan inlet o n each of two opposite sides, an elongated separator connected to each'of said inlet sides, each of said separators having an inner elongated gas conduit communicating with the inlet in the side to which it is connected,

a chamber in said T connecting said outlet and inlets, and a partition in said 'i' between said two inlets and extending to said outlet.

In testimony ,whereof I have signed my name to this specilication.
